The warp-knit tape includes a coupling element mounting portion which is inelastic in a warp direction and a tape main body portion which is highly elastic in the warp direction. A buffer area including only weft in-laid yarns, for example, for intercepting influence of acts of the coupling element mounting portion and the main body portion on each other is defined between the mounting portion and the main body portion.
